[0012] The heat dissipation capacity of this heat dissipation structure depends on the heat dissipation area of the heat sink and the air volume of the fan. The existence of the heat dissipation fan will generate operating noise and affect comfort, and the life of the fan is generally less than the life of the automotive air conditioner driver required by the electric bus manufacturer.
[0013] In addition, the car air-conditioning system is installed on the roof. After running for a long time, dust is easy to accumulate around the driver of the car air-conditioning, which affects the life of the fan and the heat dissipation effect of the entire cooling system.

The invention provides an automobile air conditioner system and a heat dissipation device of the automobile air conditioner system. The automobile air conditioner system comprises at least one driver,an electric drive compressor and the heat dissipation device. The driver is electrically connected with the electric drive compressor and used for driving the electric drive compressor. The heat dissipation device is connected with a coolant pipe of the electric drive compressor, makes contact with the driver and is used for dissipating heat of the driver. The heat dissipation device of the automobile air conditioner system comprises an upper board, a lower board and a snake-shaped coil pipe, wherein the driver is installed on one surface of the upper board; the lower board is arranged corresponding to the upper board and connected with the upper board; and the snake-shaped coil pipe directly communicates with the coolant pipe of the electric drive compressor, at least one groove used forcontaining the snake-shaped coil pipe is formed in the upper board and / or the lower board, and the lower board and the upper board jointly clamp and fix the snake-shaped coil pipe after being connected.
Description
technical field [0001] The invention relates to an air-conditioning system and a cooling device thereof, in particular to an automobile air-conditioning system and a cooling device thereof. Background technique [0002] In recent years, with the country's encouragement and support for the new energy industry, more and more automobile manufacturers have launched pure electric buses, which have been widely used in many cities. Pure electric buses mostly use low-noise, energy-saving inverter air conditioners to meet passengers' requirements for the comfort of the riding environment. [0003] The air-conditioning system is generally installed on the roof of the bus, but due to the limited installation space on the roof, the compressor and fan driver used in the inverter air conditioner generally require a flat shape and horizontal installation. In addition, because the roof of the bus is directly exposed to sunlight in summer, the working environment temperature of the air cond...
